Describe the problem/error/question

I have 2 n8n workspaces. in one, i have the ability to select 4.1 to use in my workflows.

in my other, i’m unable to see it as an optoin. what could be the issue? both are updated to the most recent version of n8n.

What is the error message (if any)?

maybe try re-auth ure key? or refresh it by adding a new one in that instance that’s not picking it up?

Maybe it just needs to pull the data again in that step? Have you tired this?

i figured it out. my client’s team only allowed certain models in the openai api workspace settings. had nothing to do with n8n!

Nice yes it states " message”: “Project proj_elK1MuwcdFW5Y8wqQEZz0PRr does not have access to model gpt-4.1-2025-04-14 ”," glad it’s all resolved :slight_smile: Have a great day.
